The graph shows the system y=2x+1 y=2x^2+1 Which ordered pairs are solutions of the system?
zhenek [66]
Hey!


To solve this problem, we would really have to graph both equations.

<em>OPEN THE FIRST IMAGE</em>

The first image I provided was the image of this equation graphed: <span>y=2x+1

<em>OPEN THE SECOND IMAGE</em>

The second image I provided was the image of this equation graphed: </span><span>y=2x^2+1


<em>PLEASE DO NOT LOOK AT THE THIRD IMAGE YET!</em>


The first image has two points. One at ( -0.5, 0 ) and the other at ( 0, 1 ).

The second image has only one point, which is at ( 0, 1 ).

<em>OPEN THE THIRD IMAGE</em>

Now, when both are combined we see that they intersect at two points, which are ( 0, 1 ) and ( 1, 3 ).

So, our answer is...

<em>The ordered pairs that are the solution to the system are</em>  </span><span>( 0,1 ) and ( 1,3 ).

Hope this helped!

Solve for 2a:<br> a + 6 = 3a + 2<br> 2a
rosijanka [135]

Answer:

Break down the problem into these 2 equations.

a+6=3a+2

a+6=3a+2

a+6=2a

a+6=2a

Solve the 1st equation: a+6=3a+2a+6=3a+2.

a=2

a=2

Solve the 2nd equation: a+6=2aa+6=2a.

a=6

a=6

Collect all solutions.

a=2,6

a=2,6

Mary is planning to provide online math and french language tutoring sessions. The math session will be 45 minutes long, and the
alisha [4.7K]

Answer:

  • 3/4m + 1/2f ≤ 30
  • f ≤ 30

Step-by-step explanation:

  • Math session = 45 min = 3/4 hr
  • French session = 30 min = 1/2 hr
  • Number of math sessions = m, total math hours = 3/4m
  • Number of French sessions = f, total French hours = 1/2f

<u>Total hours constraint:</u>

  • 3/4m + 1/2f ≤ 30

<u>Number of session constraint:</u>

  • f ≤ 30

<u>So the system is:</u>

  • 3/4m + 1/2f ≤ 30
  • f ≤ 30

Job natural peanut butter normally cost four dollars today it’s on sale for $3.60 what is the percentage of the discount
Rzqust [24]
We can make an equation that would help this. X will be the discount rate.
4x=3.60
Now, we need to solve the equation to find what X is.
Let's divide each side by 4.
x=.9
So, we know that the item was sold for 90% of what it was before, meaning that it has a 10% discount.
